ThisV invention relatesto improvements in fluid measuring and dispensingapparatus and. more particularly, toV such apparatusas is adapted fordispensing measured quantities of gasoline or thev like.

The general object of the invention is to provide in a gasolinedispensing apparatus improvements which simplify the work of theoperator and make it easier and more convenient for him to service thefuel tank of an automobile.

According to one object' of the invention, a single control member isprovided outside the pump casing mounted for movement back and forththroughout a predetermined range and operable, when moved from one limitto the other ofsuch range, to eilect a complete cycle of movement of theresetting shaft of the register and then to start the pump motor,whereby resetting ofl the register must be effected before pumping' cancommence, said member being operable when moved from the last-named tothe other limit, to stop the motor without actuating said shaft.

According to another object ofthe invention, the single control membermay be part of a swivelled mounting for the delivery hose so that as thehose nozzle is carried to the tank to be serviced, the hose willbepulled to turn the said part of the swivelled mounting and causeresetting. of the register and starting of the pump motor without anyspecial effort or attention on. the part of the operator.

According to another object ofthe invention,

the mounting includes a rigid pipe, having a` vertical portion,rotatably mounted adjacent one side of theA pump casing to turn aboutits own axis, and a transverse portion, to the outer end of which thehose is connected, this transverse portion being high enough to clearthe top of the pump casing, when such portion is turning, andl longenough to extend from one side to the other of the casing, such pipebeing turnable' to any desired position through a 360cr range to providefor convenience in servicing and for extension of the servicing range.

The invention has for another object the provision of means, preferablyinterlocked with the nozzle and nozzle support, for holding said pipe` iin one predetermined angular position, when the hose is not in use',such position being one wherein the transverse portion of the rotatablepipe overlies the top of the casing.

The invention has for another object the provision of actuatingconnections between the rotatable pipe and the register of the apparatusfor resettingV the latter by the movement of the rotatable pipe througha predetermined' angle from a predetermined initial radial position, andpreferably irrespective of the direction in which the rotatable pipeturns.

These and other objects will' best be understood from the detaileddescription of the examples of the invention with reference to theaccompanying drawings, in which:

Referring to these drawings and first to Figs. 1 and 2 thereof, theinvention is shown, by way of illustrative example, asA embodied in agasoline dispensing apparatus of well known form. Such apparatusincludes a pump I, driven by an electric motor 2, through the belt 3 andpulleys 4 and 5, and adapted to draw up fluid such as gasoline, from anunderground supply tank (not shown) through a suction pipe 5 and forceit outwardly through a delivery conduit, which includes a flexible hose"l, having on its outlet end a valved hose nozzle 8. As shown herein,this delivery conduit includes a pipe 8' connecting the outlet of pump Ito an air separator 9, a pipe I9 connecting the outlet of separator 9 tothe inlet of Va meter Il and a pipe I2 connecting the outlet of themeter, by means later to be described in detail, to a swivelled pipe I3to the outer end of which hose 'I is connected by means of a suitablecoupling I4. Interposed in pipe I3 at its highest po-int, is a visibledischarge indicator I5 of any suitable or desired form. v

The meter II, which measures the fluid dispensed, drives through a shaftI5, a register`I, which indicates the amount of iiuid dispensed inquantity, cost or both. As shown, the register is of the well knowncomputing type and has number Wheels i8, visible through openings I9 ina dial plate for showing the quantity of fluid dispensed, in gallons andfractions thereof, and other number wheels 2l visible through openings22 in said plate for sho-wing the cost of the fluid dispensed, indollars and cents. The register may, for example, be of any suitabletype, such as the well known Veeder-Root type or the type shown in theDeLancey Patent No. 2,390,239, granted December 4, 1945,

The apparatus described, except for the hose 1, and pipe I3, is enclosedin a suitable upright casing and supported from a suitable frame locatedwithin the casing in any suitable way. As herein shown, the frameincludes a base 23, angle iron columns 24 iixed to and upstanding fromthe .base and an inner cap 23, which ties together the upper ends of'the four columns. The casing has a cap 23, supported by the inner cap25, and front, back and side panels ZTI, 23 and 29, respectively, whichenclose the space between the base 23 and cap 23. The columns 24 carryplatforms 33 and 3l, the former supporting the motor 2 and pump I andthe latter the register I'I.

The swinging pipe arm i3 is mounted, as best shown in Figs. 3 and d.Extending across between a pair of the columns 24 and secured at itsends thereto is a plate 32. Bolted to this plate is a casting 33, whichextends outwardly through an opening 34 in the adjacent side panel 29.This casting has mounted therein axially-spaced upper and lower bearings35 and 33, which rotatably support the vertical portion of pipe I3. Thecasting 33 has on its upper face a race for a plurality of balls 37,upon which rest a disk 33, xcd to the pipe I3. The said upper face, thedisk and the balls serve as a thrust bearing to support the pipe I3.This `pipe is held against upward displacement by a collar fixed to itslower end and engaging the lower end face of bearing 36. Thelower end ofpipe I3 is open and in constant about twice the length of the pipe.

communication with a chamber 49, formed in a casting 4I, xed to thelower face of casting 33 and closing the chamber 43. The only othercommunication with chamber 49 is by way of the described pipe I2. rihemetered uid from pipe I2 thus flows throughchamber 40, and pipe I3 tohose l. Leakage from chamber 40 is prevented Iby two seal rings 42,which are mounted on pipe I3 between the bearings 35 and 36 and forcedapart by a spring 43 and thereby pressed, one against the upper face ofbearing 33 and the other against the lower face of bearing 35. Thecasting 33 is preferably enclosed by a casing 44, suitably fixed to sidepanel 29. Casing 44 has in its upper Vend a circular opening bounded byan upstanding annular rim 43. Fixed to pipe I3 is a circular cap 46which overlies the opening and has a downturned annular rim 4?overlapping the rim 45.

When the apparatus is not being used, the pipe I3 overlies the cap 26 ofthe pump casing, extend-- ing from oneside to the other thereof, and thehose is then disposed in a long loop, extending downwardly from theouter or free end of pipeV I3 toward the bottom of the pump casing andthen upwardly toward the top or" the casing, where the nozzle 'I restson a suitable sup-port, such as 43. The spout of the nozzle usually liesin a boot 49 to protect it from the weather and, when so located, aportion of the guard 50 for the valve lever 5I of the nozzle rests onthe support'. As best shown in Fig. 3, the guard lhas an openingtherethrough to receive an upstandingear 52 on the nozzle support 48.The ear is perforated to receive a padlock to enable the nozzle to belocked to the support. When the apparatus is used for dispensing, thenozzle is Vremoved from its supn port and carried to the tank to beserviced. In so doing, the pipe I3 will be swung to 4one side or theother of its normal or neutral position and it maybe swung throughvarying angles to extend the service range. The pipe I3, when turneddegrees from neutral position, effects the maximum increase in theservice range, which is t may be turned to a lesser extent, according torequirements, but it will always be turned at least 45 degrees fromneutral position for any servicing. Of course, the pipe can turn 360degrees, if necessary or desired.

To assist the operator in locating pipe I3 in various positions,recesses such as 53 may be provided in the periphery of disk 38 and aspringN pressed detent 54 mounted on casting 33' in position to engagein any of the recesses as the disk is turned. As shown one notch islocated so as to be engaged by the detent, when pipe I3 is in neutralposition, and the other notches are spaced at 45 degree intervalstherefrom.

Aside from the advantage of increasing the servicing range of the pump,the swivelled pipe I3 may be utilized as a control member, operable byits movement to eiect resetting of the register I'I and then thestarting of the pump motor 2, and subsequently operable to eiectstopping of the motor. For this purpose, an actuating cam is provided,fixed to pipe I3. In this case, a cam path 55 is formed in the upperface of the described disk 38 to receive a roll 55 mounted on a lever5l, which is pivoted at one end on a stud 58 fixed to an upstanding hubon casting 33. The cam path 55 is constructed so that when pipe I3 isturned through a predeterminedV angle. say for example 30 degrees, ineither direction from its neutral position, the lever 5l will be 5,;movedv its;` full stroke (to.- the left as shown in- Fig.` 4f. Furtherrotation of the pipe causes ther roll; 56: to engage in a dwell;portionof thecam, whereby the pipeV t3` canthus` turnwwithout moving;the lever; .When the pipe is turned back toits neutral` position, thelever 5T will be moved back` during the last degree part of its move-`ment, into the` position-` illustrated. ThisV lever is arranged by anysuitable transmission' to operate a. mechanism to reset the register andto actuate the switch of the pumpfrnotor' 2. herein, such transmissionconsists of a. Bowden wire. 59,. one end of which is. connected to lever5T, and a. sheath: 59?' for theV wire, one end of which sheath is held'by a suitable anchor 6I to plate 3'2; or any other: stationary part ofthea apparatus. The Bowden wire and its sheath extend across the pumpcasing over the top7 of register l1 and thendownwardly tothe mechanism`for resetting: the` register, later to be described.

In one form of register, there is a shaft 52', which, when turnedthrough a predetermined angular extent, in this case 405 degrees, in onedirection (clockwise as viewed in Fie 8) will reset the number wheels tozero. This shaft will then be. turned back, by means within theregister, through an angle of degrees, making the net movement of shaft62, 360 degrees or oneV revolution. As shown in Fig. 8, the shaft 62 hasfixed; thereon a ratchet 63 and a disk 64, having a single radial notch65 in its periphery. A spring-pressed pawl 56 cooperates with ratchet 63and is normally engaged with ratchet tooth 67'. 69? of the register andcarries near its lower end a roll Hl adapted to engage in notch 65.. Aspring 'l-I., connecting member 6-8 tosome stationary part of theregisterl tends to turn member 68V clockwiseand through roll 1G. to turndisk 64 counter:- clockwise but is unable to do so on account or theengagement of p-awl 66 with` ratchet tooth 61. rotating reversely fromVthe position shown. To reset the register, shaft 62 is turned clockwise.As-it is thus turned therst action is to movey roll 10.- to the rightand stress spring 1l.. r[his action continues for 45 degrees, when roll.1d' will'. ride out of notch y and onto the periphery of disk 64, whereit will not exert any force:4 on the disk tending to turn it backward'.During this Li5 degree interval, the usual clutches (not shown) will beactuated to disconnect each set of number Wheels from the meter drivingmechanism andthen connect them to the resetting shaft 62,A all as.disclosed in the aforesaid patent. The rst tooth12 of. ratchet 63 has.an angular extent of slightly more than 45 degrees. One canA therefore.turn shaft 62 through the initial4 45` degree movement and then move itbackward to its nor`- mal. and illustrated position. However, afterresetting has commenced, which occurs just after the initial 45 degreemovement of shaft 82 is comU pleted, the latter cannot be restoredl toits initial position. by reverse rotation because of pawl 6 and ratchet63. Shaft 62 can thenl be turnedonly in a forwardly or clockwisedirection.. Thus, resetting, once initiated, must be completed. Afterthe shaft 62 has been turnedV 465 degrees, the disk164 will move underroll lil and the latter will. drop into the notch 65. Then, spring 15|,acting through member 68. and roll: lo will turn disk 6.4 backwardly(counterclockwise)`y into the position shown, the long tooth 'l2permitting this reverse movement;

As illustrated A member 6B is mounted to swing on a shaft The resettingshaft 62 is thus held from Resetting will have been 6, completed priorto this reverse movement". of shaft: 62- and during suchl reversemovement, the` clutchesl of the `register will be: actuated to disYconnect the number wheels from shaft 6-2 .and reconnect them to thedriving mechanism. actutated by meter shaft I6.

Not all forms of registers employ reverse move--v ment` of thevresetting `shaft after the endl of the resetting movement but. thosethat do employ` such reverse movement, present specialdifli'culties` inadapting this invention for' use with them, and they will be considered'first, bearing in mind. that there. are other forms of registers,wherein` a. predetermined movement of the resetting. shafts in one*direction only willeffect resetting.

The reset shaft6-2 `(Fig. 3)' extendsfoutsidethe` casing of register |1-and has fixed to itsA outer end a socket member 13) which is connectedby meansv of a shaft 'I4 to` a socket member 15,. fixed on the inner endof a. short shaft 16which isratatably mounted in a hub ofV a plate 111and which has fixed to its other end` a pinion` T8..

The pinion is the terminal. element of the re setting gearing, whichisactuated bythe ahove= described Bowden wire 59. The plate lliislxed atitsl ends, one to each of two of the columni` 24, and supports suchgearing.. The i. shaft` 1&1 connects the two socket members 13 and 15and` allows one to be driven from the other even if' the two socketsare' not exactly aligned. Each socket member hasV a cylindrical sockettoy receive aball 19 on theend of' shaft 'M The peripheralwall of eachsocket has two. diametrically-opp' site longitudinally-disposed slotstherein, to slidably receive the projecting ends of ai cross pin 8l,fixed in` ball` 19 and extendingdiametrically therethrough. i

The reset gearing includes a gear 82,.which isr teeth. This arm 84 isconnected to the lower endv` of the described Bowden Wire 59', Vthesheath" 60 of which is anchored alt-60 to plate T1.

Thus, swinging of the pipe I3 will oscillate the pawl' arm. In thisparticular case, the cam isconstructed to swing pawl 84` through l-4of'a revolution. The ratio of gear 82 to. pinion T8, in this case, is 8to 1, the gear 82 having 64 teeth for ex'- ample, and the pinion 181having 8 teeth. The pawll 84 initially abuts one ratchet tooth as shown.when pipe I3 is in its' neutral position;

When arm I3 is moved in either direction from. neutral position, throughan angle ofA say' 30 degrees, the pawl 84 will swing upwardly 9/4 of' a.revolution and turn gear 82 counterclockwise. by the same amount, ornine teeth. This will drive pinion I8 clockwiseA nine teeth or one andone eighth revolutions and shaft 62 will thus be turned the requiredamount to complete resetting of register I1. Fixed to plate 11' is a`cam 88,. arranged in the path ofi pawl 8`4` and adaptedr when thelatter' reaches the end of its upward stroke, to release the pawl 84from the. tooth, 4

which itv had theretofore been driving. On such release of the pawl, thespring Tl; of the register will very rapidly turn the reset shaft G2backwardly (counterclockwise) by an angle of` 45 de.-

grecs. This will turn pinion. 18. one. tooth. inA a coimterclockwise`direction, whereby' gear 82 'will be turned one tooth in'V a clockwisedirection, bringing it beneath pawl 84 so that the latter, whensubsequently released from the cam 88 during the initial part of itsreturn or downward movement cannot become drivingly engaged with suchtooth. The pawl 84 will be swung downwardly just far enough to engagebeneath the next ratchet tooth of the series in position for asubsequent resetting operation in the manner described.

The switch for stopping and starting the pump motor 2 is containedwithin the casing of the motor and is usually of the toggle type. Thisswitch is operated by pulling or pushing on a Bowden wire, containedwithin a sheath 90 which, as shown in Fig. l, extends upwardly in thepump casing. The upper end of this sheath is shown in Fig. 5, fixed byan anchor 9| to a plate 92, which in turn is xed at its ends to two ofthe angle iron columns 24. The upper end of Bowden wire 93 is shown asfixed to a lever 95. Lever 94 is pivotally supported intermediate itsends on a stud 95, xed to plate 92, and has at one end a roll 96,pressed against the periphery of a cam 91 by means of a spring 98, whichconnects the lever to plate 92. The cam 91 is mounted to turn on a stud99, fixed to plate 92, and is turned by means of a link |09, whichconnects it to pawl 84. The cam 91 has a dwell surface on which roll 96rides, until the pawl 84 reaches the end of its upward stroke, when theroll rides off this dwell surface onto a steep drop |02. The spring 98would move roll 9B quickly to the bottom of this drop |92, except for adashpot |03, the piston I 94 of which is connected by its rod 05 tolever 94. The descent of piston |04 is limited by the small area of thevent |06 of the dashpot, whereby the closing of the motor switch isdelayed and made to occur after the pawl 84 has reset the register. Theswitch, being of the toggle type is not actuated until at the very endof the stroke of lever 94.

The cam 91, lever 94, spring 98 and dashpot |03 provide for a time delaybetween the actuation of the register-resetting means and the closing ofthe motor switch. This time delay, while desirable as insurance that themotor switch cannot be closed until resetting of the register has beencompleted, may not in all cases be necessary. As will later appear, theBowden wire 93 may be connected to the pawl 84 without the intermediaryof the time delay device described. Ordinarily, if the motor switch isclosed at the same time that the gear 82 has completed its resettingmovement, the 45 degree reverse movement of the register shaft 62 willbe effected almost instantaneously by spring 'II and before the operatorwill have time to open the valve of the hose nozzle and thereby causemovement of shaft I6 and the number wheels of the register I'|.

The shaft 99, to one end of which cam 91, is fixed, is mounted in abearing |01, xed to the outer face of plate 92 and extending through andbeyond the adjacent side panel 29. On the outer and upper part of thebearing is mounted the nozzle support 48, heretofore described. Suchsupport is pivoted to the bearing at |08 and is'urged upwardly by aspring |09. When the spout of nozzle 8 is placed in boot 49, the lowerand horizontal part of the guard 50 of nozzle 8 is swung inwardly anddeposited on the pivoted support 48, whereupon the latter movesdownwardly under the weight of the nozzle into the position shown, inwhich the outer end of sup- 8 port 48 lies in a recess in a collar |I0,fixed to the outer end of shaft 99. When the switch of motor 2 is openand the parts of the resetting gearing are positioned as shown, therecess in collar |I0 is positioned so as to receive the hose support 48.When collar I0 is in any other position, as it is when the motor switchis closed and pipe I3 swung out of its normal rest position, the support48 rides on the periphery of collar IIB and the nozzle 8 cannot thenv behung up. Thus the operator must restore pipe I3 to its normal or neutralposition before he can hang up the hose nozzle. When the nozzle is hungup, as described, its interlock with collar ||0 prevents the pump frombeing started, the resetting means from being actuated and the pipe I3from being swung away from neutral position.

If desired, an interlock collar III, such as shown in Fig. 10, may havea recess wide enough to directly receive the guard 50 of the hose nozzle8. In this case, the bearing |01 would then serve as a stationary hosesupport and the pivoted member 43 and its spring |09 can be elim inated.

In operation, the operator must iirst remove the nozzle 8 from itssupport 48 or |01, as the case may be, before he can swing pipe I3 bypulling on the hose. The interlockv between the nozzle and collar II orIII, as the case may be, locks pipe I3 in its neutral position againstrotation and hence prevents the operator from starting the pump motor.Having removed the nozzle 8 from its support, the operator carries it tothe tank to be serviced and, in so doing, swings pipe i3 away from'itsneutral position. Ordinarily, in moving the nozzle to the tank to beserviced, the pipe I3 will be swung far enough to actuate the resettinggearing, as described'and then close the motor switch, all without anyeiort or attention on the part of the operator. However, if the pumpdoesnt start, the operator will have to pull on the hose to swing pipe|3 far enough to effect the resetting of the register and the closing ofthe motor switch. The swinging pipe enables extension of the servicerange, whenever required, and enables easy servicing of cars on eitherside of the island, on which'the pump is ordinarily mounted. The pumpcontrol and the register resetting occur automatically by the pulling ofthe hose necessary to carry the nozzle into servicing position.

For use where hose extension by means of a swinging pipe is not neededor desired, the pump shown in Figs. 11 to 15 is provided. This pump isconstructed like the one, above described, except that the swinging pipeI3 and associated devices are omitted and the delivery hose emerges fromthe opening near the top of one of the side panels 29, the hose beingsuitably connected inside the pump casing with p-ipe I2. Suitablevisible discharge indicators I|2 are also provided in the deliveryconduit and extend through the front and back panels 2l and 28 of thepump casing, as indicated in Fig. 11. The hose nozzle 8, when its spoutis inserted in boot 49, is supported by the horizontal portion of itsguard 59 resting on `top of a fixed support H3, which is fastened at itsinner end to plate S2 and extends outwardly through the side panel 29.Near the outer end of support ||3 is an upstanding ear |I4, which passesthrough a slot in guard 50 and is perforated to receive a padlock,whereby the nozzle may be locked t@ its support.

The resetting gearingis the same as heretofore described but the controlmember, which actuates it, consists of a 'small handle |45 instead ofthe swinging pipe I3. This handle is xed to the outer end of a shaft|16, which is rotatably mounted in support |13 and has xed to its inner`end a lever |11. The outer end of this lever is connected by a link2|,I8 Ito the pawl 84 which actuates the resetting gearing. The Bowdenwire S3, which actuates the switch of the pump motor, is also connectedtoolever ||1 by means of a suitable connecting piece H9. On the innerend face of the hub of Yhandle ||5 is formed a lug |20, having radialsides adapted to abut one .or the other `of two radial stop faces |2|and |22, formed on the nozzle support H3. These stops `|21 and 4.22Alimit the extent of swinging movement of handle ||`5 to .exactly thatnecessary to swing pawl 8.4 through an angle equal to 4that .between`successive ratchet teeth and to thatnecessary to move the motor switchbetween its on and off positions. When ,handle ||5 is positioned, as.shown in Figs. 12 and 13, so that its lug |20 abuts stop |21, thepawl84 is in its extreme lower position and the motor switch is open.Clockraised far enough to .actuate the resetting .gearl ing, in the samemanner as heretofore `described, and also move the motorswitch to fonposition. When .dispensing .is finished, the operator must swing handle|I5 .counterclockwise until the lug abuts stop |2.| in order to hang upthe .nozzle on its support and, in so doing, the motor switch iis `movedto 4oiF position Vand the pawl84 is restored to its lower positioninreadiness 'for a subsequent actuation .to reset `the register. y

Another form of `thein-v-entionisillustrated in Figs. 16 to 19. Inthis,-as well-as in the iirstform of the invention, the `control memberlis the swinging pipe l|3 and it is-mounted-andioperates in the same wayas described in `connection with Ngs. .1 to `5. The `casing x44 and cap145 will be used but these have 4been omitted yin Fig. 17. However, in.addition vto cam 155, `which ractuates lthejBowden Vwire 59, a separate`path cam |24 is 4provided in a .disk .125, ,fixed .to pipe 1.3, :for:the purpose of actuating- `the `motor switch and Aa clutch, to `be.later described, in `the :resetting gearing. .A .roll |,2\3,1mounted onand depending .from 4a lever |21, rides `inl-cam 424.

Themembers |42 and V|43 abut opposite sides of the bearing for shaft 14|and serve `to retain the shaft in proper axial position. vThe outer endface of element 14d and the inner end face of element 4|43 `have teethsuchas |44, which are normally `held .engaged but maybe disengaged byaxial movement of element .|45 to the left by means of the clutch fork|35, actuated .by Bowden wire |29. This clutch element |43 'has on itsinner face a socket |45, similar to the heretofore described socket 13on the reset shaft 162 of register I1 and connected to socket 13 by ashaft |46, which has ball ends to fit in .the `sockets and cross pins inthe Vball ends .to fit in Aslots in the .side walls `of the sockets inthe same manner as'heretofore described in connec `tion with shaft 14. Aspring |41, coiled around `shaft |46, vacts :between two washers |48 onthe shaft |46 to pressagainst the .end faces of .sockets .13 and |45 andpress the clutch element |40 -toward and into engagement with itscooperating element 143.

The arm |34 `is connected by alink 1h19 to Lthe `upper end of aconnector strip |511, `the lower lend Iof which is attached to `theBowden wire :93, `which .actuates the motor switch. The strip 1.5i! .ispivotally connected at a point intermediate Vits ends to oneend of anarm I5|, the other end of which .is fixed to the inner end of the shaft:99, in place of the cam 91, heretofore described. This shaft 99 ismounted, ras before, and carries on its outer end a collar, such as 0,for interlocking with the hose nozzle support, as heretofore described.

The Bowden Wire 59, actuated `by cam 55,

serves, as in the rst form of the invention, to

oscillate .a pawl. This pawl, marked |52, is mounted in the same way as`pawl S4, and Vis engageable with ratchet teeth |53 xed to a gear |54,which is rotatably supported from plate 11 in the same way as gear 82.Gear |54 meshes with pinion |42. The ratio of gear |54 to pinion |42'9.to 1. lIhe ratchet teeth |53 are spaced 45 degrees. The cam 55 isarranged to move pawl .|52 45degrees. Thus, the gear I 54 will be turnedone eighth of a revolution on Veach upward stroke of pawl :|52 and willthus turn pinion |42, one and one eighth revolutions, which is what is`required to reset the register I1. The cam |124 is'designed not to movelever `|21 until aftercam 55 has moved pawl |52 through its completeupward stroke. Then cam VI 24 acts to move Bowden wire :|29 far enoughto cause clutch elements |40 and `|43 to disengage and Ato cause themotor switch -to move from off `toon position. Actually, `the clutchelement |43 lmoves beyond the position where its teeth disengage fromthe teeth onelement .143. `On -disengagement of the `clutch elements,the reset shaft .E2 of the lregister will move `backvvardly 45 degreesand come to rest. This occurs lbefore the end of `the stroke of arm |34,While the motor switch `is not moved to on position until the `very end`of `the stroke. Thus, the switch cannot `be closed until after theresetting `shaft `62 comes to rest. The teeth ofthe clutch elements arespaced ll5 degrees, so that when .the clutch elementsarersubsequently-moved into engagement, there will be no lost Amotionbetween them. Thus, on a subsequent clockwise movement of pinion |42,the clutch element |43 will immediately pick up and move clutch element|40 so that reset shaft will again be turned the required amount, inthis case one and one eighth revolutions.

If desired, the time delay means shown in the first form lof theinvention may be used, the cam 91 being xed to shaft 99 in place oflever I5i and the Bowden wire 93 being actuated fro-m the cam through alever which is pulled by a spring against the resistance of a dash pot.

In operation, when the operator wishes to service a car, he removesnozzle 8 from its support and the latter disengages from the notch incollar III] and allows the pipe I3 to turn. In carrying the nozzle 8 tothe tank of the car to be serviced, the pull on hose 1 will swing thepipe I3 and thus turn cams 55 and |24. The cam 55, when turned -apredetermined amount, say 30 degrees, in either direction from theneutral position illustrated will pull Bowden wire 59 and cause pawl |52to swing upwardly and through a ratchet tooth |53 turn gear |54 farenough to turn shaft I4| one and one eighth revolutions. Since theclutch elements I4|ly and |43 are then engaged, shafts |46 and 62 willbe turned clockwise by the same amount which completely resets theregister. The pinion |42 and gear |54 are held stationary by pawl |52and the register spring 1I is unable to move shaft 62 backwardly(counterclockwise) until the clutch elements disengage. These disengageafter pipe I3 has turned a predetermined amount, say l5 degrees,

further, and following the disengagement of the clutch, the motor switchis closed and pumping commences. After the desired amount of fluid hasbeen dispensed, the operator returns the nozzle to its support and, ashe does so, the pipe I3 is swung toward its neutral position. The rstaction is for cam |24 to move Bowden wire |29 to allow the clutchelements |43 and |43 to reengage and the motor switch to be moved to offposition. This is followed by the action of cam 55, which through Bowdenwire 59 will move pawl |52 downwardly until it snaps over yand behindthe next succeeding tooth of the ratchet. The nozzle cannot be placed onits support until the motor switch has been opened and this occurs onlyat the end of the swinging movement of lever I5I. Thus, the operatormust move pipe I3 completely back to neutral position before he can hangup the hose nozzle. The engagement of the spring-pressed detent 54 in anotch in disk 38 will help the operator in locating the pipe properly inneutral position.

As mentioned above, certain registers provide for resetting by apredetermined movement of the resetting shaft in one direction onlywithout the reverse movement described. As one example, one suchregister requires its resetting shaft to be turned two revolutions inorder to reset the number wheels to zero and then this shaft comes torest. The invention may very readily be arranged for use with registersof this type simply by omitting the clutch means, which permit thereverse movement, and making appropriate changes in the resettinggearing. These changes are indicated in Fig. 20. Assume that the shaft16 is connected, in a manner similar to that described, to a resettingshaft which needs to be turned two full revolutions in a clockwisedirection to move the number wheels of the register back to zero. A gear82, having ratchet teeth 85, moved by pawl 84 by Bowden wire 59,

as formerly, meshes with a pinion |55, mounted on a stud |56, fixed toplate 11. Pinion |55 has fixed thereto a gear |51, which meshes with anidler gear |58 mounted on a stud |59 fixed to plate 11 and the idlergear |58 meshes with the pinion 18 on shaft 16. As an example, gear 82has 64 teeth, the ratchet teeth 85 are spaced 45 degrees, pawl 84 has astroke of 45 degrees, pinion |55 has 8 teeth, gear |51 has 16 teeth andpinion 18 has 8 teeth. Thus, the pawl when pulled upwardly by Bowdenwire 59 will turn gear 82, one eighth of a revolution counterclockwiseor 8 teeth. This will cause pinion |55 and with it gear |51 to be turnedone revolution clockwise. Gear |51 through idler gear |58 will turnpinion 18 in a clockwise direction and the full two revolutions requiredfor resetting. The link |06 may connect pawl 84 as before to actuate themotor switch, closing it when the pawl reaches the end of its upwardstroke. While pumping occurs, the resetting shaft of the registerremains stationary and all of the gears described will remainstationary. After the desired amount of iiuid has been dispensed, thepipe I3 is returned to neutral position, thereby pushing on the Bowdenwire and moving pawl 84 downwardly without moving gear 82, the pawlfinally coming to rest beneath the ratchet tooth next succeeding the onewhich it had theretofore driven. Also, the motor switch will be openedwhen pawl 84 reaches the end of its downward stroke.

In all forms of the invention a relatively simple mechanism is providedfor resetting the register and controlling the pump motor so thatdispensing cannot occur until the register has been reset and so thatresetting cannot occur during dispensing. This is effected simply byswinging a control member (the pipe I3 or handle ||5 or equivalentmeans) from one extreme to another of a predetermined range of movementand without any necessity for the relatively complicated and expensiveinterlocks, heretofore used between the pump control lever and theregister-resetting shaft.

The invention also provides, in the case of the swinging pipe I3, ameans whereby the resetting of the register and starting of the pump areeffected, without requiring any particular attention or effort on thepart of the operator, by the act of moving the hose nozzle into positionto service the tank of an automobile.

The swinging pipe I3 also enables easy servicing of the tank of anautomobile from either side of the island, on which a pump is oftenmounted. and enables a desirable extension of the servicing range, sincethe pipe can swing to any position throughout a 360 degree range. Also,the extension of the hose is effected without requiring extra exertionon the part of the operator as is required, where spring-retracted reelsor other spring or weight-retracted hose-storage means are used. Suchreels or means require the operator to pull the hose out against theresistance of the retracting spring and to hold it extended undertension. Here, the extension requires no substantial added effort. Theoperator simply carries the nozzle, wherever he wishes to go, and thepipe swings as much as required and in the direction required, andduring the initial stages of the swinging in either direction resettingof the register occurs followed by starting of the pump motor.

Thus, substantially improved means have been provided for controlling auid dispensing ap 13 "paradis, iiiateriaii'y Simplifying andfacilitating the rservicing of the fuel tanks of automobiles.
